Implement "Add transaction" dialog

Instructions

Our bank app is still missing one important feature: the possibility to enter new transactions. Using everything that you've learnt in the four previous lessons, implement an "Add transaction" dialog:

• Add an "Add transaction" button in the dashboard page
• Either create a new page with an HTML template, or use JavaScript to show/hide the dialog HTML without leaving the dashboard page (you can use hidden property for that, or CSS classes)
• Make sure you handle keyboard and screen reader accessibility for the dialog
• Implement an HTML form to receive input data
• Create JSON data from the form data and send it to the API
• Update the dashboard page with the new data

Look at the server API specifications to see which API you need to call and what is the expected JSON format.

Here's an example result after completing the assignment:
